The following example shows how to manually set up a controlling bridge (CB) with
three attached bridge port extenders (BPEs) in a two-tier structure (see CB with Two-Tier BPEs
Topology).
CB with Two-Tier BPEs
Topology
Attach BPEs.
On the CB, enable VPEX mode:
X465.1 # enable vpex
X465.1 # reboot
Are you sure you want to reboot the switch? (y/N) Yes
Slot-1 VPEX X465.1 #
Note
After reboot, command prompt changes to show that you are in VPEX
mode.
Create LAGs between CB and first-tier BPEs:
Slot-1 VPEX X465.1 # enable sharing 1:10 group 1:10-1:11 lacp
Slot-1 VPEX X465.2 # enable sharing 1:20 group 1:20-1:21 lacp
Configure slot identifiers associated with the
first-tier BPEs:
Slot-1 VPEX X465.1 # configure vpex port 1:10 slot 110
WARNING: This command will remove VLAN membership from the
port 1:10.
Do you want to continue? (y/N)Yes
Slot-1 VPEX X465.2 # configure vpex port 1:20 slot 120
WARNING: This command will remove VLAN membership from the
port 1:20.
Do you want to continue? (y/N)Yes
Slot-1 VPEX X465.3 # show slot

Note
Observe that the show slot command shows the CB as
slot 1 with the two BPEs as slots 110 and 120.
Note
Observe that the show vpex command shows that
ports 1:10 and 1:20 are the cascade ports connecting to the BPEs.
Create LAG between first-tier and second-tier
BPEs:
Configure slot identifier associated with the
second-tier BPE:
Slot-1 VPEX X465.1 # configure vpex port 110:49 slot 130
WARNING: This command will remove VLAN membership from the
port 110:49.
Do you want to continue? (y/N)Yes

Slot-1 VPEX X465.2 # create vlan v100 tag 100
Slot-1 VPEX X465.3 # configure vlan v100 add port 130:1-2, 120:1-2, 1:7 tagged
If required, you can use standard show commands to
troubleshoot the network from the CB using the counters:
